Context that
knows what matters.

Sulci doesn’t just capture everything — it captures it intelligently. Every atom is classified, scored, and prioritized so the most important knowledge is always available when you need it.

⭐

Core Atoms Always Injected

When Sulci injects context before your message, Core atoms (importance ≥ 0.75) appear first under a “Core Knowledge” header — always, regardless of query match. Your most critical facts are never skipped.

🏷

Auto-Flagging on Capture

The LLM extractor automatically assigns semantic flags (CORE, DECISION, TECHNICAL, PREFERENCE) and importance scores when atoms are captured. Instructions auto-score 0.9, decisions 0.85. No manual work.

⌛

Expiry-Aware Sidebar

The context sidebar filters expired atoms in real time. Set a valid_until date on any atom and it disappears from context automatically when it’s no longer relevant — sprint goals, deadlines, temporary decisions.

Three steps to
